So I am trucking my '89 F250 7.3 IDI from Fairbanks, AK to North Carolina. I made it to Calgary, Alberta yesterday and started having the battery dummy light on the dash flash when RPMs would drop on the highway and would come on constant at a stop light. I replaced the pigtail to the voltage regulator (only about 2 months old Motorcraft) and ran a new ground and thought it had solved the problem until it started happening again. I found a replacement alternator here in Calgary and got it swapped and all was running great. Measured voltage with a multimeter and even the cluster VM was happy sitting straight up and down. All was great until I went to the airport and out of habit pushed my parking break down (it doesn't even work that well) and as soon as I got one click into the ebrake my VM, oil pressure gauge and cluster lights go out. I am at the Stampede all day tomorrow with my mother. All cables in the truck are brand new with multiple brand new grounds. I am hoping this is just a simple fix, but would love and very much appreciate some opinions or ideas to attempt for tomorrow night when I can dive into it. Please and thank you, guys and gals! This truck has to make it another 3,000 miles roughly to NC. I would like to do it with being able to see my cluster and hopefully it's not anything major. Maybe a fuse? I haven't tested anything yet. It's just parked in the parkade down the block. Just irks me that this happened right after my new alternator install. Fixing one problem to have another pop up. Please help thanks!
